SAWING-MACI-IINE AND THE LIKE.

T 0 all whom it may concern:

Be it known that we, ADOLF JULIUS TE- NOW and J OHAN EDWARD BosTnoM,subjects of the King of Sweden, residing in Stockholm, in the Kingdom ofSweden, the latter temporarily in St. Petersburg, in the Empire ofRussia, have invented new and use ful Improvements in Sawing-Machinesand the Like, of which the following is a specification, reference beinghad to the drawings accompanying and forming a part hereof.

This invention relates to improvements in sawing machines and the like.

In sawing crooked or curved timber along its curvature the deviceshereto employed have usually been placed in the path of the timberoutside the machine frame, i. e. in front of the said frame or behindthe same.

The object of the invention is to make it possible to place thecontrivances for sawing curvilinearly within the machine frame properwhich is advantageous in several respects, above all as regardssimplicity and easy attendance.

In the drawings, we have shown a sawing machine embodying the invention.

Figure 1 is a front view of the machine frame with the contrivances foradjusting the rolls. Fig. 2 is a plan view and partial horizontalsection along the line AB of Fig. 1. Fig. 3 is a detail view showing inelevation the crank shaft for adjusting the rolls in position. Figs. 4and 5 show diagrammatically in what manner the rolls may be adjusted inone direction or the other.

Referring to the drawings, 1 is the machine frame and 2 are cross beamsattached thereto. J ournaled in the said cross beams and in the upperpart of the machine frame are axles or shafts 3 transmitting motion bymeans of bevel gears 7 and 8 to rolls 4 and 5. The said rolls arejournaled in frames 9 and 10 adapted to swing about the shafts 3 withoutthe engagement of the bevel wheels being disturbed. The upper frames 10are also movable up and down on the shafts 3 together with the bevelgears 8. The swinging of the frames 9 and 10 with the rolls 4 and 5 iseffected by axles or shafts 11 journaled in the cross-beams 2 and inbearings 12 attached to the machine frame 1. The

pins 13 of the shafts 11 journaled in the Specification of LettersPatent.

so that the latter are swung along a circular are when the pins areturned. The shafts 11 are engaged by jaw-like sleeves 1 1 at the frames9 and 10, and the openings in the sleeves corresponding to the shaftsare oblong in the longitudinal direction of the frames, in order toenable the shafts to.

swing. Connected to the lower pins 13 of the shafts 11 is a suitablelever mechanism connected to both shafts 11 in such a manner as toalways turn both shafts equal angles in opposite directions.

It appears from the aforesaid that, when the shafts 11 are swung abouttheir pivot pins 13, said shafts act to swing the frames 9 and 10 withthe rolls 4 and 5 journaled If the shafts 11 are swung away from eachother so are also the rolls (see Fig. 4E), and if the said shafts areswung toward each other, as shown in Fig. 5, the rolls are also swunginwardly toward each other. In both cases the rolls, on account of theiroblique positions, will feed the crooked timber in such a manner as tocause the same to be sawed along its curvature.

We claim:

1. In a sawing machine, the combination of a stationary frame, verticalshafts mounted in the said frame, upper and lower frames adapted toswing about the said shafts, said upper frames being also movablevertically along the said shafts, rolls journaled horizontally in thesaid swingable frames, and means for adjusting the said swingable framesin position about the said shafts.

2. In a sawing machine, the combination of a stationary frame, verticalshafts mounted in the said frame, upper and lower frames adapted toswing about the said shafts, said upper frames being also movablevertically along the said shafts, rolls journaled horizontally in thesaid swingable frames, and crank shafts engaging the said swingableframes for adjusting same in position relatively to the stationaryframe.

3. In a sawing machine, the combination of a stationary frame, verticalrotary shafts journaled in the said frame, upper and lower framesadapted to swing about the said shafts, said upper frames being alsomovable vertically along the said shafts, rolls journaled horizontallyin the said swingable frames, means for imparting rotary movement fromthe said shafts to the said rolls, and means for adjusting the saidswingable frames in position about the said shafts.

4- In a sawing machine, the combination of a stationary frame, verticalrotary shafts journaled in the said frame, upper and lower framesadapted to swing about the said shafts, said upper frames being alsomovable vertically along the said shafts, rolls journaled horizontallyin the said swingable frames, means for imparting rotary movement fromthe said shafts to the said rolls, and crank shafts engaging the saidswingable frames for adjusting same in position relatively to thestationary frame.

5. In a sawing machine, the combination of a stationary frame, verticalrotary shafts j ournaled in the said frame, upper and lower framesadapted to swing about the said shafts, said upper frames being alsomovable Vertically along the said shafts, jawlike sleeves arranged inthe said swingable frames, rolls journaled horizontally in the saidswingable frames, means for imparting rotary movement from the saidshafts to the said rolls, and crank shafts engaging the sleeves of theswingable frames for adjusting the positions of the rolls.
